Dormer Pramet A976 3.60 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

The Dormer Pramet A976 3.60 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Drill is built for precision, versatility, and depth. Designed for professionals who tackle demanding holes, this drill delivers clean starts, reliable repeatability, and the reach you need in tight or recessed workspaces.

Why this drill stands out

• 130° point for easy starts – The sharp, self-centering point reduces wander and lowers the push force required to begin cutting, helping you achieve accurate hole locations from the first stroke.
• Bright finish for smoother operation – The polished surface minimizes material sticking to the cutting edge, reducing built-up edge and improving chip flow, especially with challenging metals.
• Parabolic flute design for deep holes – Engineered to evacuate chips efficiently in long through-holes, this flute geometry supports a single-pass drilling approach with less clogging and smoother hole walls.
• Premium HSS-E material – This high-performance alloy is suitable for drilling a range of materials, including steel, aluminum, and stainless steel, delivering durability and reliable performance across applications.
• Extra long length series – Specifically designed for very deep holes and applications requiring extended reach, it pairs with a straight shank for stable, accurate cutting in challenging geometries.
• DIN 1869 / 1 compatibility – The drill format aligns with standard industry requirements, ensuring dependable interchangeability with compatible chucks and holders.

Ideal uses and scenarios

Crews in machine shops, automotive, aerospace, and general metal fabrication will appreciate the A976 drill for deep-hole tasks where a standard length bit would fall short. It shines when drilling through thick materials or when access is limited to a narrow bore, such as precision jigs, fixtures, or component housings. Its multi-application capability means you can switch seamlessly between steel, aluminum, and stainless steel without swapping tooling.

Tips for best results

For optimal performance, pair the drill with appropriate speeds and feeds for your material, and use a reliable cutting fluid or coolant to manage heat in deep-hole work. Start at conservative speeds to establish a clean entrance, then adjust to maximize material removal without sacrificing edge life. Ensure the drill is properly secured in a rigid chuck or collet to minimize runout, especially given the extended length.
